The traditional Chinese medicine(TCM) quality constant herbal slices evaluation method was applied to evaluate the grade of Sophorae Tonkinensis Radix et Rhizoma based on the combination of traditional character identification and modern scientific and technological methods. The TCM quality constant evaluation method was used to determine the appearance and index content of medicinal slices, calculate the quality constant and percentile quality constant of Sophorae Tonkinensis Radix et Rhizoma from different sources, and discuss their classification. The quality constants of 15 batches of Sophorae Tonkinensis Radix et Rhizoma slices were between 0.004 and 0.063. The slices with the percentage quality constant ≥80% were classified as the first grade; those with the percentage quality constant ≥50% and <80% were classified as the second grade; and those with the percentage quality constant <50% were classified as the third grade. Then the slices with the quality constant ≥0.050 were classified as the first grade; those with the quality constant ≥0.032 and <0.050 were classified as the second grade; and those with the quality constant <0.032 were classified as the third grade. According to the results, the 15 batches of Sophorae Tonkinensis Radix et Rhizoma slices were divided into 1 batch of the first grade, 4 batches of the second grade, and 10 batches of the third grade. The quality constant evaluation method established is scientific, objective, simple and feasible. The application of the method in Sophorae Tonkinensis Radix et Rhizoma slices has reasonable results, which is helpful to promote the classification of Sophorae Tonkinensis Radix et Rhizoma and promotes the high-quality application of Sophorae Tonkinensis Radix et Rhizoma.
采用中药质量常数饮片评价方法，基于传统性状鉴别与现代科技方法相结合，对山豆根饮片等级进行评价。运用中药质量常数评价方法确定饮片外观及指标成分含量，计算不同产地山豆根的质量常数及百分质量常数，并探讨其分级情况。15批山豆根饮片的质量常数在0.004至0.063之间。百分质量常数≥80%的饮片列为一级；百分质量常数≥50%且＜80%的列为二级；百分质量常数＜50%的列为三级。再将质量常数≥0.050的饮片列为一级；质量常数≥0.032且＜0.050的列为二级；质量常数＜0.032的列为三级。结果显示，15批山豆根饮片分为一级1批、二级4批、三级10批。所建立的质量常数评价方法科学、客观、简便、可行。该方法在山豆根饮片中的应用结果合理，有助于推动山豆根的分级，促进山豆根的优质应用。
